Fame
You could be the "rabbi to the Stars" and spend your life guiding the spiritual lives of the rich and famous.
You could also be a respected Orthodox Rebbe and have hundreds of thousands of followers.
Or you could appeal to the TV audience and be a rabbi with your own talk show or be Oprah's rabbi with his or her own radio show.
Beyond that, you're just the person who gets smiled at and waved to on the way to the deli.
